Distill documents: PostgreSQL + AI agent

Fires the moment a webhook arrives across PostgreSQL, Twilio and Slack, hands the decision to an AI agent with its own tools, then branches on the check before anything is written. Built for newsletters, around a "Normalize Draft Payload" step, in 17 documented nodes.

Distill documents with PostgreSQL and Twilio without manual work. An original, ready-to-import n8n workflow built around the 'AI Summarize & Route' pattern for content creation & media. It fires on a webhook and orchestrates 17 nodes across PostgreSQL, Twilio, Slack. It uses n8n's LangChain AI nodes (Agent/Chain + chat model). Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Your team sees the right data at the right time.

Key benefits

  • Keeps PostgreSQL and Twilio in step for newsletters, without anyone re-typing a row
  • A failed PostgreSQL or Twilio call is retried rather than dropped, at any of the 17 nodes in this newsletters build
  • Branches rejoin before PostgreSQL, so a newsletters run reports once rather than 17 times
  • The newsletters AI step is isolated from PostgreSQL, so models swap without touching the other 17 nodes
  • Fans the same result out to Slack in the same run, for newsletters

Use cases

  • Teams keeping PostgreSQL and Twilio aligned by hand for newsletters
  • Newsletters work that needs a judgement call per item before it reaches PostgreSQL
  • Pushing newsletters events into PostgreSQL and Twilio the moment they land, not on the next poll
  • Newsletters work where "Normalize Draft Payload" is still a manual step before PostgreSQL

Agent tools included (2)

An AI Agent is only as capable as the tools wired into it. These are read from the template's own graph — every one is a real node in the file you download.

  • Lookup API Data · HTTP request
  • Run Calculations · Calculator

Conversation memory is attached, so the agent carries earlier turns of a session.

From download to running in 3 steps

  1. 1
    Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
  2. 2
    Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
  3. 3
    Activate. Run it once to test, then toggle Active. The automation is live.

What you'll learn

Advanced level

Adds branching depth and audit logging on top of the core pattern.

  • Routing classified output into separate action branches
  • Rejoining parallel branches with Merge so the run reports once
  • Moving data between PostgreSQL, Twilio and Slack in a single run

Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.

Common questions

What exactly do I get?

The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.

How do I import it into n8n?

In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.

Do I need anything else for it to work?

You need your own n8n instance and accounts/credentials for the apps this workflow connects to (PostgreSQL, Twilio, Slack, HTTP / REST API). No coding is required.

What if it doesn't work for me?

If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.

Can I modify or resell it?

You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
